Description

Technical Field

[0001] The present invention relates to the field of audio technology, and in particular to a directional audio system with a noise reduction component. Background Art

[0002] In the continuous evolution of audio technology, directional audio has demonstrated a wide range of application value in many fields such as conferences, performances, and home entertainment due to its unique audio directional propagation capability. The core of directional sound wave control technology lies in its unique algorithm design. By accurately calculating the propagation path and diffusion angle of the sound beam, this technology can concentrate sound energy in a specific direction to achieve directional propagation of sound. The implementation of this technology is inseparable from complex mathematical models and algorithm support. In actual applications, directional sound wave control technology will dynamically adjust the shape and direction of the beam according to factors such as the placement of the speaker and ambient noise to ensure that the sound can be accurately transmitted to the target area, while minimizing the diffusion of sound in other areas. Its core purpose is to achieve directional propagation and enhancement of sound by precisely controlling the propagation direction and shape of the sound waves.

[0003] However, as directional speakers continue to improve in performance, the complexity of their internal mechanical components has also increased significantly. This change has directly led to increasingly serious problems with vibration and noise generated during operation. Traditional directional speakers rely on passive noise reduction materials such as sound-isolating foam and shock-absorbing pads. While these materials can suppress noise transmission to a certain extent, their effectiveness is insufficient under high-load conditions, and the noise problem remains prominent, seriously affecting the user's listening experience.

[0004] In addition, since there are many electrical components inside the directional speaker, a large amount of heat will be generated during long-term and continuous operation. If this heat cannot be dissipated in a timely and effective manner, it will inevitably cause the temperature inside the speaker to rise, which will pose a serious threat to its performance stability and service life. Traditional heat dissipation methods, such as natural wind heat dissipation, although they can alleviate the heat dissipation pressure to a certain extent, have low heat dissipation efficiency and cannot meet the dual requirements of modern directional speakers for efficient heat dissipation and low-noise environment. Especially when operating at high loads or used in confined spaces, the limitations of natural wind heat dissipation are particularly obvious, which often causes the speaker to overheat, thereby affecting its normal operation. In response to the above problems, the present invention document proposes a directional speaker with a noise reduction component. Summary of the Invention

[0019] Compared with the prior art, the present invention provides a directional speaker with a noise reduction component, which has the following beneficial effects:

[0020] 1. The directional speaker with a noise reduction component is equipped with an active structure, a first noise reduction structure and a conversion structure. When the directional speaker body is started and plays audio, vibration of its internal mechanical parts is inevitable. In order to effectively slow down and absorb the noise generated by these vibrations, this directional speaker introduces an active structure, the core of which is a movable plate that can move up and down. As the sound vibration is transmitted, the movable plate moves up and down accordingly. This dynamic process not only directly acts on the first noise reduction structure, squeezing or stretching it through physical contact to absorb part of the vibration energy, but also, the movement of the movable plate triggers the linkage mechanism of the conversion structure. Since the diameter of the second gear is larger than that of the first gear, according to the principle of gear transmission, the moving distance is effectively amplified, and the motion range of the second gear plate is expanded, so that it can more significantly adjust the position or state of the second noise reduction structure, thereby achieving more extensive absorption and buffering of the noise generated by the vibration of the movable plate and the directional speaker body, further enhancing the noise reduction efficiency of the directional speaker.

[0021] 2. This directional speaker with a noise reduction component is provided with a heat dissipation structure and an air guide structure. During the operation of the speaker, the vibration of the directional speaker body not only drives the movable plate of the noise reduction component to vibrate up and down inside the installation cabinet, but also achieves an amplification effect of the movement distance through a precise gear transmission mechanism, in which the diameter of the second gear is larger than the first gear, so that the movement distance of the second gear plate significantly exceeds the direct movement distance of the movable plate. Then, through the linkage action of the vertical plate, the adjustment plate is prompted to move quickly and effectively inside the installation cabinet, thereby promoting changes in the air flow inside the installation cabinet. In order to effectively manage the heat generated by the operation of the directional speaker body, the heat dissipation structure is carefully designed to include an S-shaped first and second heat dissipation pipes. These heat dissipation pipes are made of high-efficiency heat-conducting materials. Designed to quickly absorb and disperse the heat generated by the directional speaker body, the air guide structure consists of a first air guide duct and a second air guide duct, which are cleverly embedded in the interior of the installation cabinet to form a closed-loop air circulation system. As the adjustment plate moves, the air flow inside the installation cabinet is guided to the first air guide duct and the second air guide duct, and then the air is guided to the first heat dissipation pipe and the second heat dissipation pipe. In this process, the air not only provides the necessary convection heat exchange conditions for the heat dissipation pipe, but also accelerates the dissipation of heat through the flow in the pipe, thereby effectively reducing the operating temperature of the directional speaker body and ensuring that the speaker can maintain a safe temperature range even under long-term high-load operation, ensuring the stable operation and long-term durability of the speaker, and providing users with an excellent listening experience and equipment reliability.

[0022] 3. The directional speaker with a noise reduction component is equipped with a protective cover. Since it is arranged on the outer wall of the installation cabinet and is fixedly connected to the bottom of the directional speaker body and the top of the connecting plate, it can fully block external rainwater, making it difficult for external rainwater and foreign objects to enter the interior of the installation cabinet, and has a certain protective effect on the first gear, the second gear, the first tooth plate and the second tooth plate, further ensuring the service life of the directional speaker.

The first heat dissipation pipe 701 and the second heat dissipation pipe 702 are made of high-efficiency heat conduction materials. By setting the heat dissipation structure 7 and the air guide structure 8, during the operation of the audio, the vibration of the directional audio body 2 not only drives the movable plate 301 of the noise reduction component to vibrate up and down inside the installation cabinet 101, but also realizes the amplification effect of the movement distance through the precise gear transmission mechanism, that is, the diameter of the second gear 603 is larger than the first gear 602, so that The moving distance of the second tooth plate 605 significantly exceeds the direct moving distance of the movable plate 301, and then through the linkage effect of the vertical plate 504, the adjustment plate 501 is prompted to move quickly and effectively inside the installation cabinet 101, thereby promoting the change of the air flow inside the installation cabinet 101. In order to effectively manage the heat generated by the directional audio body 2, the heat dissipation structure 7 is carefully designed to include an S-shaped first heat dissipation pipe 701 and a second heat dissipation pipe 702. These heat dissipation pipes are made of high-efficiency heat-conducting materials and are intended to quickly absorb and disperse the heat generated by the directional audio body 2.

A closed-loop air circulation system is formed inside the cabinet 101. As the adjustment plate 501 moves, the air flow inside the cabinet 101 is guided to the first air duct 801 and the second air duct 802, and then the air is guided to the first heat dissipation pipe 701 and the second heat dissipation pipe 702.

By setting the telescopic frame 901 and the shielding cover 902, when the directional sound is installed outdoors, with the cooperation of the telescopic frame 901 and the shielding cover 902, the directional sound body 2 can be shielded from wind and rain, thereby providing a certain degree of protection for the directional sound body 2 and ensuring the service life of the directional sound.

[0045] Working principle: When the directional audio body 2 is working, vibration is generated, causing the movable plate 301 to move up and down inside the installation cabinet 101, and the movable plate 301 squeezes or pulls the first telescopic rod 401 and the first spring 402. At the same time, when the movable plate 301 drives the first tooth plate 604 to move, under the action of the rotating shaft 601, the first tooth plate 604 drives the second tooth plate 605 to rise or fall through the first gear 602 and the second gear 603. Since the diameter of the second gear 603 is larger than the diameter of the first gear 602, the moving distance of the second tooth plate 605 is greater than the moving distance of the first tooth plate 604, so that the adjustment range of the second tooth plate 605 on the adjustment plate 501 becomes larger, so that the second spring 503 can further buffer and reduce shock on the movable plate 301 and the directional audio body 2, thereby achieving the effect of noise reduction;

[0046] When the directional audio body 2 is working, it drives the movable plate 301 to vibrate up and down inside the installation cabinet 101, and since the diameter of the second gear 603 is larger than the diameter of the first gear 602, the moving distance of the second tooth plate 605 is larger than the moving distance of the movable plate 301, so that the second tooth plate 605 drives the adjustment plate 501 to move quickly inside the installation cabinet 101 through the vertical plate 504, so that when the air inside the installation cabinet 101 changes, the air inside the first heat dissipation pipe 701 and the second heat dissipation pipe 702 can be adjusted through the first air duct 801 and the second air duct 802, so that it flows quickly, thereby having an auxiliary heat dissipation effect on the directional audio body 2.

[0047] The above are only preferred specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
